GLASS LOADING SPOUT FOR GRAIN ELEVATORS.

Application filed October 9, 1922. Serial No. 593,238.

To all whom it may concern.

Be it known that I, HIRAM C. I-IoLs'r, a citizen of the United States, and resident of Genoa, in the county of Lincoln, State of Colorado, have invented certain new and useful Improvements in Glass Loading Spouts for Grain Elevators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form apart of this specification. g

The object of this invention is to provide a spout construction for grain elevators which shall have long life and will reduce friction to a minimum in order that the grain during the operation of loading a car may be projected well back into the car and thereby eliminate shoveling.

Briefly the invention comprises a spout composed of a plurality of sections, each section being formed of glass of such toughness that it will withstand the usages of grain loading'and will have little or no Wear. The interior of each section is perfectly smooth in order that friction will be largely eliminated, and the lower ends of the sections which are tapered to fit into the larger ends of sections next lower are provided with a protecting band of some shock absorbing material that will prevent direct contact of glass surfaces and take up shocks or jars to avoid breakage.

In the accompanying drawings wherein certain embodiments of the invention are disclosed by way of illustration,

Fig. 1 is a view partially in vertical section and partially in elevation showing two spout sections connected with the elevator;

Fig. 2 is an elevation of a single section made of wire-reinforced glass, portions being broken away;

Fig. 3 is a sectional detail on line 33 of Fig. 2;

Fig. 4 shows how a plurality of sections cooperate when curved to direct grain back into a car or the like;

Fig. 5 is a sectional detail showing the handle mounted on the lowermost section.

The spout in order to be flexible is composed of a plurality of spout sections 10 in the usual manner, and each section is made of glass or like material which is sufiiciently hard and tough to resist wear and reduce friction to a minimum. If desired, the sections may be reinforced with wire 12 as shown in Fig. 2 so that in the event of breaking the sectionwould not fall away. The sections all taper downward in order that they may partially telescope with the lower end of each section within the upper end of the section next below. In order to prevent engagement of the glass surfaces when so assembled, the lower end of each section is provided with an annular band or buffer of some shock absorbing material such as. leatheror molded rubberized fabric asindicated at 14.. If desired the lower end both of the band and of the section may be beveled 0d at 15 where no contact takes place. Each band or buffer is suitably secured to its spout section 10, a convenient method residing in the provision of an annular rib on the outer face of the section over which the band 14: may be sprung until the rib 16 engages in a groove in the band, this method being particularly desirable where molded material is used for the buffer.

, The lower portion of each section is re duced in thickness for the purpose of receiving the band or buifer 14, and each band is thicker than the depth of the cut-out portion of the section, in order that the face of the band or buffer 14 may lie at all points beyond the line of the face of the section 10. In this manner, when the sections are telescoped more than when in operative position, as when removing the end of the spout from a car, the additional thickness of the bufi'er continues to prevent contact of the surfaces above the buffer. The length of each buffer band 14 may be such as to rise above the upper edge of the section next lower when in any operative position (Fig. 1 and Fig. 2) including curved positions, or such that when the sections are in extreme curved position as in Fig. 4 the inner faces adjacent the upper edges of the lower sections will still engage the upper edge of the buffers and prevent contact of the glass portions. The essential thing is the pre vention of any contact which would result in breaking. cracking or chipping.

The uppermost section of the spout will engage "over the 'lOWer end of a nozzle or discharge sleeve 20 secured to the elevator E andhaving thereon a protecting band 22 similar to bands 14. The spout sections are supported by means of a pair of chains 24 disposed at opposite sides of the spout, links of these chains 24 engaging eyes 25'carried' by metallic retaining straps 26'' held" in grooves 28 formed in the sections. The ends 30 of straps 26 are offset forming. earswhich. are clamped together by bolts 31, said straps being cushioned in the grooves 28 by means of strips of felt or the like 32. The chains 24 may be disconnected from a section 10, by merely removing the nuts 33 and slipping off, the eyes-or loops 25engaging, the chains, whereby a section may, be replaced if'neces5 sary.

The end section 1 10 is. provided. with a handle 34. carried; by a pair Of ands or straps 35 carried in grooves likethestraps 26. By means of, this handlethe spout may be manipulated,asdesiredto directlthe grain being discharged.

The glass. has long life and: the friction ofthe moving grain; uponthe glass is sniall, with the result, that, holes. are not worn through the sections. to interfere with: the, movement of the. grain and the stream of, grain moves rapidly from the; end v of. the. spout being thereby projected. well back into the end of'a car being loaded. After loading, the sections may belifted. upward from thefouter endso as to telescope. the: spout sufiiciently for removal from the car. door, the buffer bands 14; preventing; contact of. the glasspartsl and insuring against break/- ing or. cracking; Thus the spout has the two-fold advantage of efficiency and long life. The absenoeof nuts andboltheadsollthe interior further insures minimum friction.

I claim:

1'. A hollow grain spout section having a body of'tough. glassand a protecting'band on one end thereof.

2. A hollow grain spout section having a glass body and a, countersunk supporting band on the outer face thereof.

3. A hollow grain spout section having a tapered glass body, a protecting device about, the-smaller end thereof, and, a counter-- sunk supporting member about the larger end, thereof.

4. A hollow grain spout section having a glass body providedwith a ribvtherearound, and a protecting. band having. a, groove engaging. over said rib.

5. grain spout having a plurality of; sections of, glass, the lower ends ofsaid section. being reducedin size, and. projecting into the upper ends of thenext lower sec; tions, and protecting means about said'lower ends-the lines, of whose faces lie beyond; the linesof the faces of the upper portions of the sections. I

6 A grain spout having a plurality of telescoping sections of; glass, the lower ends of the sections proj ecting'; into the. largerends,

of adjacent sect'ionsandjhaving limited, mo: tion therein laterally, and protecting. means bet-ween opposed facesofv said lower and.

larger ends. I

In testimony whereof I; affix; my signature.
